Patient satisfaction and behavioural intention in using the home medication delivery service in an ambulatory oncology centre

Background The COVID-19 pandemic has increased usage of medication delivery service (MDS) significantly. MDS improves adherence to medication and clinical outcomes. Objectives To study behavioral change factors that affect adoption of MDS, determine existing patient satisfaction level, and make recommendations to improve MDS adoption. Methods A single-institution, cross-sectional survey was conducted at the outpatient pharmacy of the largest ambulatory cancer centre in Singapore. The survey consisted of sections on demographics, Theory of Planned Behavior constructs and patient satisfaction questions. Descriptive analysis and logistic regression were used. Results A total of 881 patients responded. Respondents were mostly Chinese, female and subsidized patients, with a mean age of 62.4 years old. MDS use is strongly predicted by favourable attitude (OR 3.54, 95%CI 2.64-4.75; p < 0.001) and subjective norm (OR 3.07, 95%CI 2.30-4.09; p < 0.001) towards its use and greater perceived behavioral control (OR 2.48; 95%CI 1.86-3.30; p < 0.001). Being ill or frail has been identified as facilitators, while absence of face-to-face consultation and cost of delivery were barriers to the adoption of MDS. Encouragingly, the satisfaction level of our existing patients was generally high (80.2, SD16.7). Recommendation to improve MDS adoption targets facilitators and barriers identified and aims to further elevate patient satisfaction level. Establishment of a centralised pharmacy for MDS together with a call centre would be essential in the long run. Conclusions MDS is becoming increasingly important, in line with our national strategy. Implementation of suggested short-term and long-term measures will encourage its use.
